           Product: digikam
           Version: 4.11.0
          Platform: MacPorts Packages
                OS: OS X
            Status: UNCONFIRMED

          Assignee: digikam-devel at kde.org
          Reporter: gsking1 at gmail.com

Tried to import and got a crash.  
I have tried with 2 cameras an iphone 6 ( auto detected as an iphone5 (PTP))
and a Canon S95.  Both crash when trying to import.  The autodetect process and
dialog seems to work okay. 



Reproducible: Always

Steps to Reproduce:
1.  Connect iphone
2. Select camera listed ( e.g. Apple iPhone 5 (PTP)
3.  Crash

Actual Results:  
No imported pictures and a crash.

Expected Results:  
Import with no crashes
